The Interception Tilt Rotor Specter (Spectre in some localizations) is the Grand Canyon boss from Strikers 1945 III.
In Battle Edit
Specter appears as a helicopter form with two sets of propellers. He can fly around to battle the player. When you defeat this form, he will transform into a stag beetle. Watch out for the bullets and then he reveals the blue orb. When the blue orb disappears, he continues to battle with the player, spinning his body in a corkscrew motion. He then fires a barrage of bullets while spinning. First, you will try to avoid the bullets when damaging Specter. When you defeated Specter, he explodes and you earn money or rubies. Failing to defeat Specter in time will cause him to cast off his shell before self-destruction.
